Is this thermostat ok?

Cold running replace it & chuck the others also, they are sticking open.
I hear you, budget we've all been there, but that equates to choke on for longer = more fuel & at todays prices of fuel!

Gee Iv'e never paid more than $42 retail for a "Genuine standard" thermostat.
4 models MK GQ GU & R32gtr over something like 15 yrs or so.
Maybe my local dealer noticed more sales if common replacement parts are fairly priced, customers return more often!.
I usually price gen if after a spares now & then they are competitive and 99% of the time a better product also.
Used to work spares a long time ago and have a fair handle on prices.

I paid $45 for the above and genuine ones are way way dearer than that to the point feeling like getting robbed.

The older thermostats aren't sticking open per say, but starts opening at around 64 degrees celsius or so and fully opened by 76-78 degrees or so, so effectively causing the engine coolant to stay bit colder that the desired temperature I reckon. I have no idea what happens once the thermostat is inside the engine though. I may be sticking open once opened inside the engine, but didn't do that on outside tests.

Agree with that thing about going cheap to find out that it's eactually expensive.
I has happened to me couple of times or so in the past, where I tried to save cash and ended up costing more.
If the aftermarket one isn't doing it's job, then that's exactly what might happen to me in this case, but
I still have the choice of returning it and getting a factory genuine one.
